The inclusion of ARP bolts for the connecting rods signifies a focus on reliable assembly strength.

When building a performance LS1 engine, especially for racing, a balanced rotating assembly like this is a critical starting point. It ensures the core of your engine is properly weighted and ready to be assembled. Please note that this assembly is not CARB approved and cannot be shipped to California.
